The Shanghai Folios 上海圖書館藏殘葉
These two folios were discovered in the bindings of a Jiajing period edition of Tao Yuanming Ji 陶淵明集 in the collection of Shanghai Library (see Shen Jin 沈津, “Chu Ci ji Han, Wei, Liuchao bieji” 《楚辭》及漢、魏、六朝別集 in Wen Xian 44 (1990.2) pp.189-200).
Unfortunately the two folios are identical copies of the same folio of text, and the all-important central fold (版心) is not visible in the reproductions (remaining hidden within the binding of the host edition).
My thanks to Shen Jin for providing me with the photocopies of these folios (West 1992).
